Pete Cooper 65a6b57c33 Added instcombine pattern to spot comparing -val or val against 0.
(val != 0) == (-val != 0) so "abs(val) != 0" becomes "val != 0"

Fixes <rdar://problem/10482509>

dated tests are actual bug tests, whereas the named tests are used to test
for features that the this pass should be capable of performing.
